    There is built-in protection for surge voltages. However, cables for communication that may be subjected to overvoltage must have a primary protection, for example Protrol OVP. As a rule of thumb, one can say that cables that leave the building / station must be supplemented with a primary protection.

  • Page 10: Service Interface

    Service Interface The built-in web server in IPC402x gives authorized access to all settings, status information, file transfer etc., either via Ethernet RJ45 or USB type B. Protrol recommends using Chrome or Firefox web browsers. Connecting using Ethernet The prerequisite for connecting via Ethernet is that the service computer has IP settings that match, i.e., the same subnet and subnet mask, with those of the IPC device that you want to connect to.

  • Page 11: Connecting Using Usb

    Connecting using USB It is also possible to connect using USB type B. to do so, a separate software, Protrol USB Bridge for Windows 7/10, is needed. This is available on Protrol's website. Below is a brief description of how to connect via the program.

    100..10000 Earth Fault, General The IPC402x devices have two types of earth fault detectors; Protrol's patented method and a complementary non-directional earth fault function that can be employed when switching onto faults. The non-directional function can also be used to detect fault connection, that a phase is missing or that one phase is connected with the wrong polarity.
